First up to face off against the Acura RDX is the BMW X3. Right from the start, the RDX enjoys a significant price advantage over the X3 when comparing base trim levels. Value is just one key advantage that Acura holds over BMW. When it comes to performance, the X3 is simply no match for the RDX. In addition to significantly more horsepower and torque, the Acura RDX also boasts a more advanced 10-speed automatic transmission for greater responsiveness and a lower curb weight that contributes to more agile handling.

Shifting our attention towards interior refinement, the Acura RDX continues to shine. A standard power sunroof lets you enjoy fresh air and natural lighting inside the RDX. Similarly, both the driver and front passenger of the RDX will appreciate the standard heated front seats on chilly mornings. Both features are expensive options that BMW X3 shoppers will have to shell out additional cash for. The clever Tire Fill Assistant feature found on the RDX is not available in any form on the X3. Finally, greater cargo room and a longer term of powertrain warranty coverage round out the extensive list of advantages for the Acura RDX.

Our next challenger to go up against the Acura RDX is the Cadillac XT5. Looking at base trim levels, the starting MSRP of the RDX is $2,845 less than the XT5. Outstanding value is a core strength of the RDX which we’ll investigate further.

Standard features found on the RDX add convenience, style, and confidence while Cadillac shoppers will have to reach deeper into their wallets in order to receive similar equipment. Heated seats for the driver and front passenger, a power sunroof, and an auto-dimming rearview mirror are each examples of standard features on the RDX. Larger 19-inch wheels offer a more stylish look than the 18-inch wheels on the Cadillac.

When it comes to performance and efficiency, the Acura RDX delivers more than the Cadillac XT5. Not only does the RDX have greater torque than the XT5, it’s also more fuel efficient. A more sophisticated 10-speed automatic transmission contributes to the MPG figures while providing greater response.

Driver-assistive technologies help inspire confidence behind the wheel of the Acura RDX. A standard Collision Mitigation Braking System can apply the brakes automatically to help avoid a potential collision.

Last up, we’ll investigate how the Acura RDX fares against the formidable Mercedes-Benz GLB. Although the Mercedes-Benz begins with a slight price advantage, a closer look reveals that choosing Acura actually proves to be the smarter financial decision. Beginning with performance, the GLB is simply no match for the superior horsepower, torque, and transmission included as standard with the RDX. Larger 19-inch alloy wheels give the RDX a more prominent stance on the road as well.

Inside the cabin, drivers will immediately be drawn to the expansive 10-inch touchscreen display of the RDX. Other premium amenities included as standard inside the RDX are a power sunroof, heated front seats, ambient interior lighting, an auto-dimming rearview mirror, and automatic high beam headlights.
